{"Image DocumentName": "4 Stroke engine 2\u00ba Compression.", "Image ImageDescription": "Both exhaust and intake valves stay closed as the piston move upward from the BDC (bottom dead center) The piston moves upward, squeeze the fuel-air mixture into a smaller volume. The pressure gets higher and this causes the fuel-air mixture\u00b4s temperature to rise. With high temperature, ignition is easier and combustion more complete.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
